Closed-Cell Insulation

HBS closed-cell spray foam insulation outperforms traditional insulation by providing an air, water and vapor barrier in a single component. Spray foam insulation adheres to most surfaces and expands to create a seamless, airtight building envelope. In addition, it offers outstanding high-performance options for commercial, residential, institutional, industrial or agricultural applications.
